The EdgeMax ERLite-3 from Ubiqiti Networks is based on the multi-core 64- bit MIPS architecture SoC from Cavium. This board has Linux and BSD based distributions freely available online. The OS is booted from on board USB flash storage so rapid development is straightforward.
Typically this board benefits from a higher end MIPS core for applications requiring more processing power and networking.
